Application June 19, 1935, Serial No. 27,442

2 Claims. (01. 221-95) This invention relates to gasoline dispensing pumps, and more particularly to gasoline pumps used in bus terminals in dispensing large quantities of gasoline, as in the filling of gasoline tanks of buses, trucks or the like.

An important object of the invention is to provide means which may be set to automatically dispense a predetermined quantity of gasoline, eliminating the necessity of an attendant watching or checking the filling of the tank and operating the nozzle valve, when the desired quantity of gasoline has been dispensed.

With the foregoing and other objects in view which will appear as the description proceeds, the invention consists of certain novel details of construction and combinations of parts hereinafter more fully described and pointed out in the claims, it being understood that changes may be made in the construction and arrangement of parts without departing from the spirit of the invention as claimed.

In the drawing Figure 1 is an elevational view of a tank showing a gasoline pump equipped with a device constructed in accordance with the invention.

Figure 2 is a diagram of the circuits and switches, forming a part of the device.

Figure 3 is a sectional view taken on line 3--3 of Figure 1.

Figure 4 is a sectional view taken on line 4-4 of Figure 3.

Referring to the drawing in detail, the reference character 5 designates the body portion of a gasoline dispensing pump, which is of the well known construction, the pump including the usual dial 6, and hands I, that indicate the quantity of gasoline passing through the pump.

The dial includes a rim 8 that extends outwardly from the face thereof, the rim '8 providing a support for the adjustable contact supporting member 9 which is constructed of insulating material and clamped over the rim 8, in a manner as shown by Figure 3, so that the supporting member 9 will be held in position on the rim by its frictional contact with the rim, but free to slide thereover.

A pair of contact members III are carried by the contact supporting member 9 and are of such lengths that they lie in the path of travel of the long hand I of the indicator, the contact membeing provided a choke coil IS in the circuit to reduce the current passing from the main power line to the magnet l2. The return wire to the magnet I2 is indicated by the reference character H, the wire I! being in circuit with the wire 5 it through the switch l3, which is of the manually controlled type. Wire connects with the wire l3 and also has connection with the wire ill of the power line.

The magnet I2 is associated with the pivoted 1 switch member 22, which includes an arm 23, and an arm 24, the arm 23 carrying a contact member 25 that is in circuit with the magnet 26 through the wire 21, the return wire to this latter circuit being through the wire l3, there being 15 provided a resistance coil 28 between the magnet 26 and line H.

Mounted on the arm 23 is a contact arm 29 having a contact pointv adapted to engage the contact point 30 that connects with the wire 3i which leads to the contact arm 32. The contact arm 33 associated with the contact arm 32 is in circuit with the magnet 82, through the wire 32.

Mounted on the contact arm 24 is a. contact member 35 that is constructed to bridge the con- 25 tact points 36 and 31 completing the circuit to the magnet l2, through the wires 38 and 39. The wire connects with the wire 3| and wire 23, whereby the electric current may pass to the arm 32, when the switch member 22 is in its 30 normal or inactive position,

The magnet 26 is carried on the nozzle of the filling hose, the nozzle being indicated by the reference character 4|. The nozzle 4| is of the usual and well known construction and is pro- 35 vided with a valve 42, operated by means of the lever 43, actuated by the hand of the attendant. Mounted on the free end of the lever 43, is a magnet 44 that is attracted by the magnet 26, when the lever 43 has been operated to move 40 the valve 42 to its open position, the magnet 26 holding the lever 43 against the valve, maintaining the valve open.

From the foregoing it will be seen that should it be desired to dispense 40 gallons of gasoline, 45 the contact supporting member 9 is moved to a position directly over the numeral 40 of the dial of the indicator. The switch member i3 is op- 'erated completing the circuit to the magnet l2 which moves the arm 23 to cause the contact member 29 to engage the contact member 30. The magnet 26 is now energized, and the attendant operates the lever 43 moving the member 44 into engagement with the magnet 26, the magnet 26 being'energized, holding thelever 43 in its position to hold the valve 42 open, whereupon the gasoline flows through the nozzle.

when the hand 1 engages the contact mem- .bers ll, moving the contact members into engagement with each other, the circuit to the magnet 28 is shorted, whereupon the lever 43 moves away from the valve 42, allowing the valve 42 to close and cut of! the passage of gasoline through the nozzle.

Having thus described the invention, what is claimed is:

1. The combination with the manually controlled valve of a gasoline pump filling nozzle and the operating lever thereof, of an electric means for holding the valve open, said means including an electro-magnet mounted on the nozzle, an armature on the lever and attracted by the electro-magnet, an electrically controlled means operated by the gasoline flowing from the pump,

for shorting the circuit to the magnet =deenerg izing the magnet releasing the valve.

2. The combination with the manually con I trolled operating lever 01 the valve 01! a gasoline filling nozzle and hands or the dial 0! the gasoline pump, of an electric control means for holding the valve open, said control means including an electro-magnet mounted on the nozzle, an armature on the lever and adapted to be attracted by the magnet, contact members on the dial 0! the pump, wires providing an electric circuit between the contact members and magnet, and one of the hands of the dial adapted to engage the contact members shorting the circuit to the magnet deenergizing the magnet and releasing the lever whereby the operating valve is moved to cut off the flow of gasoline through the nozzle.
